To cLZZ.whom it may concern:

Be it known that I, ALBERT SncHnIs'r,

citizen of the United States, residing in the city land county of Denverand State of Colorado, have invented certain new and useful Improvementsin Chandeliers; and I do'declare the following to bea full, clear, andexact description of the invention, such as will enable 'others skilled.in vthe art to which it appert'ains to make and use the same, referencebeing/had tothe accompanyingdrawings, and to the characters of referencemarked thereon, which form a part of y invention 'relates toimprovements in general character set fort-h in previous patents issuedto me, and numbered 1,017,694, dated February 20, 1912; 1,024,369, datedApril 23, i912, and 1,024,809, datedApril 30, 1912. A

My present invent-ion relates to certain improvements over theconstructions disclcsedv n 1n the aforesaid patents,

whereby the variousv parts of the chandelier structure are more securelyconnected, and danger of dainaging insulation -of Wires located in thechandelier is made practically negligible.

Having -out-lined in a gene 1al way my present improvement, I willproceed to describe the same in detail, reference being made to theaccompanying drawingin which is illustrated an embodiment thereof.

In this drawing: Figure 1 is a section taken through a'chandelierembodying my F ig. 2 is a fragmentary detail view illustrating themanner of connecting one of the end ittings, shown on a lei-ger scale.Fig. 3 is a sectional view on the line 3-3 of the same. Fig. 4-

a detail View of a screw-pin, constituting an inimy improvement. Fig. isa View similar to Fig. 2, but showing a slightly modified form 6 is afragmentary view of the inner extremity of one`of the tube arms, shownon a larger scale than in Fig. l.

The same reference charactersl indicate same parts in all the views.

`Let the numeral 5 designate a. fixture body in which is located a tubeconnector 6, which is supported in the said body and connected with tubearms 7 which enter the iixture body through openings '8 inopposite sidesthereof, the inner extremities of the of construction. Fig.

the tube arms being fitted over nipples 9, screw-pins 10 being employedto connect the tube arms with the nipples of the tube connector. Thisscrew-pin has an enlarged threaded part 12 adjacent its head extremity,while the remaining portidn 13 of the pin isof less diameter andunthreaded. In applylng these pins the` enlarged threaded parts l2engage slots 4 formed in the tube arms and threaded openings formed inthe nipples 9 on one side. The extremities of the plain portions of thescrew-pins enter registering openings formed in thetubes and nippleslonthe opposite side from' the said vslots and threaded openings` the said4registering openings being plain or nn'- threaded. In making thisconnection, it is only necessary to apply the screw-pins to the nipples9, care being taken not to insert the said pins far enough to causetheir plain or unthreaded extremities to extend beyond the nipplefUnderthese circumstances the headsv of the screw-pins will extend above thenipples to permit the connection ot' the tube arms with the nipples, thetubes being so arranged that the mouths of the slots et are inalineinent with the threaded portions of the screw-pins. The tubes arethen moved toward the shoulders of the tube coni'iector wherebythetlireaded portions oi the screw pins are caused to engage the slots4.-

As soon as the adjacent extremities not the t-iibe arms are inengagement with the .shoulders ofthe tube connector, the tube arms aregiven a partial rotation to cause the screiv-pins to enter the otlsetportions oit' the slots 4, thereby Jformingij bayonety jointconnections. The screw-pins are then inserted to their limit of movementwhereby their headsv are caused to engage the tube arms, While theiropposite extremities are iiassed through the registering 'openingsformed in the nipples and tube arms on the opposite side troni the slotsand threaded. openings in the saine parte. 1df'here the angular slotilis employed, it will be seen that the tube arms are t. ubi); locked tothe tube connector, .since thc tube arms cannot be removed without'iiist unscrewing the screw-pins tar enough to lisci'igage their plainextremities from the openings in the tube arms, and then giving the tubearms a partial rotation to bring the screw-pins into aiineinent with theportions of the slots' 4;

extending parallely with the axes of the tubes. For this reason it i'.ill be understood that the angular slots may be dispensed with andstraight slots employed if desired. By virtue of this peculiarconstruction ot the screw-pins and thev arrangement of the perforationsthe assembled parte may be' quickly connected and disconnected, ascompared with cases where screws whose shanks are threads ed theirentire length, are employed.

To the tube connector 6 is further applied a lower spacing sleeve 1 andan upper spacing sleeve 2. The inner extremities ot these-sleeves engagethe connector 6. A rod 3 is` passed through the central opening 14formed in the tube connector and through theupper and lower sleeves ofthe structure. The upper extremity of this` rod -isvtl'ireaded into ajoint '15, a lock-mit 16 being applied to the upper extremity offthe rodand interposed between the upper extremity of the spacing sleeve 2 andthe lower end ot the joint 1 5. The lower end otrthe spacing sleeve 1engages the bottom ofv the fixture body 5 surrounding the opening in thebottoni of the said body, throng-li which the rod 3 extends. Applied tothc lower threaded extremity oit this rod, and fitted against thebottoml of the canopy on the outside, is a nut- 17 which is countersunkin a recess 1S formed in the bottom knob 19 whose perforation 2() isthreaded to receive the rod. The upper extremity of this bottom knob isfitted closely against the bottom of the canopy on the outside.

To the outer extremities of the tube arms are applied end fittings 21upon iwhich are formed nipples 22 which are inserted in the outerextremities Vof the tube arms and secured thereto by screw-pins 10 ofthe con-4 heretofore described. These screw-pins, by virtue of the'facttliat they pass entirely through the nipples and the tubular partswith which the nipples are connected, make it impossible for the.connected parts to become loose, consequentlyY there is no tendency forone part to inove or rock upon the other in such a manner struction thatthe insulation on the electrical con` ductors which must pass throughthe connected .part-s, might become worn or destroyed.

The screw-pins 10 which connect the end fittings with the tube arms maybe einployed in connection with slots 24 of ausrular shape, whereby abayonet joint is formeck-see Fig. 2,-or with straight slots 2i,-see Fig.5.

rl.`he lower extremity of a tube stem 2O is connected with a nipple 27formed on the upper extremity of the joint 15, by means of a screw-pin10, the said nipple of the joint inserted in the lower end of the saidstein. 'This connection is made in the same which the said pins engage,-

manner as the other screw-pin connections heretofore described. Theupper portion of this stem extends into a ceiling canopy Q9 which issupported on the tube stem by a set-screw 29 passed vthrough an openingformed in a bead 30 formed on the lower extremity of the ceiling canopyand surrounding the tube stem. The inner extremity of the set-screwengages the tube-stern with sutiicient force to maintain the ceilingcanopy iii its proper position of vertical adjustment. i

with tlieuppei` extremity of the tube'stem, is ay fixture stud 3l whichis lconnected with the top of the tube stem by means of a'bolt BQ, a nut33 beingapplied, the connection is snlhciently loose to permit thechandelier to hang in a vertical position.' rlhe upper extremity of thefixture stud is threaded into the lower end of a joint 34, whose upperextremity is connected, as shown at'35, with an insulating joint 36,this insulating joint' being connected with a member 37 located in aceiling cavity 38 in which is set an inverted cup-shaped member 39 whichis surrounded, and normally entirely concealed, by the ceiling canopy. f

i From the foregoing of assembling the various parts thereof, will bereadilyunderstood. For instance, 1n applying the their limit of movementthus securely locking the end fittings in place. The other screwpiiiconnections will be made in substantially the same manner, and need notbe described in detail. By virtue of my iinproved screw stem connectionsheretofore described, the said parts are much more quickly and easilyjoined than by any of the devices heretofore employed; for instance,referring to the manner of connecting the tube arms 7 with the tubeconnector 6, it is only necessary to apply the tubes to theiiipples withthe screw-pins properly adjusted. The operator. then can pass ascrewdriver downwardly from the top of the fiX ture body and readilyscrew the pin to po- Within the ceiling canopy, andv connecteddescription, my 'im-,I proved construction, as well as the mannercausing the being made in such a manner that the joint end fittings tothe tube arms, the

shown in Fig. 3, whereby their plain or unj to enter the offset portionsof the slots, after I which the screw-pins will be inserted to. Y

' extremities of the rod for vductors which thermore, by virtue of myimproved construction, it becomes l'iracticable to shift the tubeconnectors, the en d fittings and the Joints employed in connection withthe lower extremities ot the screw stems, with the4 screw pins `inplace, thus greatly facilitating the work of assembling the partsfAttention is called tothe fact that my improved screw-pin connectionsare equally applicable to parts which are square, or ot other polygonalshape in cross' section.

However, when the parts to be connected are of polygonal shape it willbe understood that the straight form of slot 25 will be employed, sincethe angular form of slot is only practicable where one part can bcrotated upon the other, at least to a limited extent.

Attention is also called to the fact that the .tube connector G, thetube arms 7, the upper and lower spacing sleeves and the rod 3 passingthrough the said connector and the said sleeves constitute a rigidlyassembled structure independently of the fixture body,

the screw-pins being employed to connect the tube arms with the tubeconnector and the nuts 16 and-17 applied tothe opposite securing tliespacing sleeves in position, It, therefore. results that if the fixturebody were injured or destroyed, the rigidity and security of thestructure would not be interfered with. Itshould be stated, further,that the important object of having the portions 'of the screw-pinsplain or unthreaded where they pass through the` openings in thenipples, is that there is nddanger of lin'` juring the'insulation 4ofthe electrical conmust pass through' these openings. In cases where theconnecting screws are threaded'throughout their length,

the sharp. edges of the screw threads are liable to destroy theVinsulation on the conductors, as the latter are drawn therethrough, 'orduring use.

Ha ving :thus described invention, what' I claim is:

1. A chandelier having openings on opposite sides, tube arms enteringsaid openings, a tubeconcomprising a fixture body l' nector within thefixture body, the said connector having nipples which enter vtheextremities of the tube arms, and screwpins for attaching the tube armsto the said connector, the said pins having threaded portions adjacenttheir heads, the connected parts being perforated to receive thescrewpins which pass entirely through the same,

.one set of the perforations in the nipples being threaded to receivethe threaded portions otthe screw-pin, substantially as described. l

2. A chandelier comprising a fixture body, a tube arm connectorlinclosed within the fixture body, said connector being verticallyperforated, a rod passing through said perforation, upper'and lowerspacing' sleeves engaging the tubearm connector at opposite ends,tl1elower spacing sleeve being interposed between the said connector and thebottom' .of the lixture body, the lower extremity of the rod passingthrough an opening formed in the bottom of the fixture. body and beingthreadech'a bottom knob applied to the said threaded end, and a nut alsoapplied to said threaded end and countersunk in a recess formed in thetop of the knob.

'3. The combinationof a tube,

-a part. equipped with a tubular nipple,

and a 'screw-pin having a threaded part adjacent its head, and a plainor unthreaded part beyond, the tube and nipple having a slot andthreaded opening` respectively on one side adapted to receive thethreaded part of the screw-pin, and registering perforations on theopposite side to -receive the plain or unthreaded portion of thescrewnn. I 4. A chandelier including a tube'connector, radially disposedtube arms applied to the. tube connector and rigidly secured thereto,upper and lower spacing sleeves whose inner extremities engage the tubeconnector, a rod passed through the spacing sleeves and an openingformed in the .fronnector, the rod having threaded extren'iitiesextending beyond thesleeves, and nuts applied to the oppositeextremities ot the rod.

.in testimony whereof I atiix my signature in presence of two witnesses.
